It goes without saying that Naomi Campbell has friends in high places (very high). But the saddest part about the last few years is that the world lost many of incredible talents and revolutionaries, most of whom were part of Naomi’s entorage.

The renowned supermodel made an appearance on Watch What Happens Live and shared memories of some of her most famous celebrity friends that have since passed, including Whitney Houston, Princess Diana, George Michael and Gianni Versace.

One memory about Whitney in particular was when the superstar singer sang at Gianni Versace’s funeral: “She was Versace’s favorite artist,” Naomi said. “He wanted her to sing at his memorial at the Metropolitan museum and she sang a cappella. I remember I was sitting next to Elton John. She sang and this bird flew above – you know that skyline they have there? This bird just flew and Elton and I were like, ‘That’s Gianni.’… She was very protective of me. She was such a great lady.”

Another memory the model had was about Princess Diana during a visit to Kensington Palace with her supermodel friends Christy Turlington and Claudia Schiffer. “[Princess Diana] opened the door herself and we were in shock!” Naomi remembered. “I saw her several times — she really was a lovely lady. She really was. And really curious to know about our world, and what went on in the fashion industry. The last time I ever saw her was her telling me at Gianni Versace’s funeral how much she loved me and how sad she knew I was.”
